摘要: Longitudinal extension and consequent destruction of spirally wound membrane modules arranged in paired axial alignment within a pressure vessel an ultrafiltration unit are prevented by pair end-cap anti-telescoping devices (ATD's) central ATD. The ATD (120) is integral assembly perforated circular steel plate (112) solid interconnector (126) that concentrically disposed at its hub section (123) with tubular ends protruding on each side the having outer peripheral groove for o-ring (129) near end sealingly engaging modules. Londitudinal membranes plurality axially lugs (128) (122) proximal permeate tubes flat, faces (12) membranes.
